dbmail-3.2.1 3 problems with dbmail-imapd

Hi.

I Try to install dbmail-3.2.1 on test mailserver.

Please help to resolve 3 troubles.
Is this centos problems or dbmail bugs?

All three troubles present in dbmail-3.2.1, dbmail-3.2.0 and dbmail-3.1.17.

I have server with dbmail-2.2.12 on CentOS 5 x86_64 - this server works 
properly.
(without second and third troubles).



OS - Centos 7 x86_64 (minimal) + all needed for dbmail software (only 
epel repo)
mhash - 0.9.9.9 compile from source (sourceforge).


dbmail-3.2.1 from source
../configure --prefix=/opt/dbmail-3.2.1 --with-zdb=/usr --with-sieve 
--with-pic --with-check --with-jemalloc=/usr
make

I have 3 troubles:


(1)First:
